X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Progress Energy Executes Contract for New Nuclear Station

LCG, January 6, 2009--Progress Energy yesterday announced that it signed a $7.65 billion contract for two planned nuclear reactors to be constructed at a greenfield site in Levy County near Crystal River, Florida. The contract scope includes nuclear engineering, procurement and construction (EPC) by Westinghouse Electric and The Shaw Group. The total cost of the nuclear power station is estimated to be over $17 billion.

Progress Energy Florida, a subsidiary of Progress Energy, plans to install two Westinghouse AP1000 reactors that each have a nominal electric generating capacity of 1,100 MW. The AP1000 design incorporates passive safety features that rely upon natural forces and was certified by the Nuclear Regulatory Commission (NRC) in 2006. The NRC is now reviewing a Westinghouse application, submitted in May 2007, to amend the certified design.

In April 2008, Progress Energy announced that it had executed a letter of intent with Westinghouse Electric and The Shaw Group Inc. to purchase long-lead materials for the nuclear reactors.

In July the Florida Public Service Commission approved the proposal submitted in March by Progress Energy Florida for a determination of need to build the two reactors, with the first reactor scheduled to be operational in 2016, and the second reactor in the following year.

On October 6, 2008, the NRC accepted for review, a combined construction and operating license (COL) application submitted in July by Progress Energy Florida for the new nuclear station in Florida.
